    产品信息

    The Microchip Technology Inc. 24LCS21A is a128 x 8-bit dual-mode Electrically Erasable PROM.This device is designed for use in applicationsrequiring storage and serial transmission of configurationand control information. Two modes of operationhave been implemented: Transmit-Only mode andBidirectional mode. Upon power-up, the device will bein the Transmit-Only mode, a valid high-to-low transition on the SCLpin will cause the device to enter the Transition mode and look for a valid control byte on the I2C™Compatible bus. If itdetects a valid control byte from the master, it will switch into Bidirectional mode, with byte selectable read/write capability of the memory array using SCL.If no control byte is received, the device will revert tothe Transmit-Only mode after it receives 128 consecutiveVCLK pulses while the SCL pin is idle. The24LCS21A also enables the user to write-protect theentire memory array using its write-protect pin. The24LCS21A is available in a standard 8-pin PDIP andSOIC package in industrial temperature range.
